To @ZZ whom t may concern:

Lancaster,`in the county' of Lancaster and State of Pennsylvania, have invented certain new and" useful IImiarovem'ents'in Slidring-Shackle Locks, of which the following "'is' a specification.

rlhis invention relates to locks, and more particularly to sliding shackle locks for 'use l'on vautomobiles and other vehicles to prevent tires from being stolen.

l The invention resides more specifically in a'stop means for preventing the insertion ofthe shackle inthe wrong end'or bottom of the lock block, body'or casing, and further resides in the particular shape of the' shacklev whereby the same, in combination with the-lock body or casing, firmly clamps' the lugs to be secured together and 'guards against rattling or other noise that otherwise might` be caused by fthe shackle of the lock 'striking against the lugs' during thet'ravel of the' automobile or vehicle over the roadway. v f' ln the accompanying drawings:

Figure 1"represents a vertical cross-sectional viewthrough a portion of a'spare tire rack of ordinary construction incom-rv mon use onautomobiles, illustrating the ap- T"plica'tion of my improvedlock, shown in side elevation, to the securing lugs byiwhich a mounted tire or casing is fastened to the rearof a vehicle;

and

Referring now in detail to the drawings,

the lock block, casing or body, comprises two plates A and B preferably riveted together by means of rivets C preferably integralwithone kof the'plates. These plates between them enclose the usual lock mechanism, iiotshown, with the @usual barrel E,

of this sliding shackle type ofwloclgvfand are sorformed that when riveted together they will provide the usual twov parallel bores or passages from top to bottom tore#` ceive'the respective arms lof the'sliackle-D, the arms of whichV arefparallel, or substan- .tiallyparalleh Awithreach other up to a-point near the loop end ofthe shackle, starting-at which point each; arm isbent in a straight inclinedline toward the other arm, as-yat l, for an appreciable distance, and then the ends of these inclined portions l are connected to each other' by an intermediate,

'preferably arcuate, bar 2,fthe iiiclinedwporl'-A `tions l and thebar. or rod 2 together forming-a loop with flattened side portions.

The free Aend portions of the arms have their opposed faces providedy with notches las usual for engagement by the usual 'lock-1' ing bolts'of the usual locking mechanism. The'key-hole is located. in the bottom of the barrel E and is accessible only from the bottom of the lock casing, thatis, that part of the lock casing or body farthestaway from the bar or rod 2, an'd when so arranged it is manifest easy access can be had tothe key-hole for insertion of the usual key- K 4under all conditions to work the lock mechanism, but Yit has been found that many users `rod 2 andfwill then,l force said body or casing on said arms kto such degree that itis impossible to get aA key-.into the key-hole by reason-of thewinterference of bar or rod 2, or of the parts held' bythe shackle D, and it is therefore important'to provide an easy manner of preventing' such inisapplication of parts', and at the same time to avoid any special construction or cross-sectional form ofthe arms of the shackle or of the passages, it being important to have as few manufacturing operations as -possible to speed upA production and to'keep'f down expensev of manufacture. 1' i With the above considerations in view I provide a yielding spring pressed stop, preferably in the form of a leaf spring 3, mount# -ed-so as to extend into-one of the passages in the block, bodyor `casing for one of the arms of the shackles and adapted to yield and be `displaced from s aid Vpassage by the said arm of 'die shackle as the latter is ini serted, from the top of the lock bodfy7 or casshackle arm should an attempt be made to insert the shackle into the bottom of the lock 40 or casing. and to effectually prevent such misapplication of parts.

In the present embodiment in order to have the spring stop or yielding stop function as above described I secure leaf spring 3 by means of a rivet 4 passing through its upper end portion and the wall of plate A, with its leaf portion inclined downwardly and away from the wall of plate A into the lower part of the opening for one of the arms of the shackle, thus, as the end of the arm of the shackle, in its insertion from the top, strikes the spring 3 it will strike against the inclined inner surface thereof and force the spring 3 out of said passage, while if it be attempted to insert the shackle from the bottom the end of one of the arms of the shackle will strike against the end edge of the spring 3 and will be completely blocked thereby against further insertion in the lock body or casing.

The letter F designates the skeleton rim forming partA of, and supported by, the usual iron tire rack, not shown, with which most automobiles are provided for carrying spare tires. A demountable rim G adapter to have mounted on it a pneumatic tire or spare casing, is loosely i'itted over the rim F. A metal lug H, bolted or welded, or both, to the rim F is provided with a notch or recess in its upper end, a perforation intermediate its ends and a bolt hole near its lower end, and an opposing removable lug I, of usual type, having its lower' portion downwardly inclined away from lug H and provided with a perforation and bolt hole registering with the perforation and bolt hole in lug H and preferably, also, having a registering recess in its upper end, is normally tensionally held by a bolt and nut J with its adjacent face of its inclined portion in engagement with the demountable rim G, forcing the latter over on rim F and also spreading rim G radially, to secure the rims F and G together and prevent any relative movement between these rims.

Therwalls of the perforation and recess ihn the lug H have abrupt edges, as shown in To lock the removable lug I to the lug H to prevent unauthorized removal of the rim G with the spare tire mounted thereon, the shackle D has one arm passed through the registering perforations with the other arm lying in the registering recesses in said lugs H and I, the lock body, block or casing is then applied, as above described, to the free rezaba@ tween the lock parts and said lugs.

In the modification illustrated in Figure .5, instead of the separate rivet a for fasten,-

ing the spring 3 to plate A, I have provided a rivet stud lil formed integrally withplate A and adapted to have itsend spread down over and against the adjacent portion of the spring 8 after the latter has been applied to said stud 4a. Otherwise the construction, and operation is in all -respects'the same as in the form previously described.

Having thus described my invention,

what I claim as new and desire to secure by` Letters Patent is:

1. In a sliding shackle lock, the combination of a sliding shackle having a loop at one end and an arm, with a lock casing having a passageway through it to slidably receive an arm of said shackle and suitable mechanism having means adapted to extend into said passage to engage said arm to lock the same in said passage, and means extending in said passageway adapted to be engaged by said arm and forced out of the said passage thereby when the said arm is inserted from the top of the lock casing, and engaging the end of the arm and obstructing said passageway and preventing the insertion of said arm when an attempt is made to insert said arm from the reverse direction with respect to said lock casing.

2. In a sliding shackle lock, the combination of a sliding shackle having a loop at one end and an arm` with a lock casing having a passageway through it to slidably receive an arm of said shackle and suitable mechanism having means adapted to extend into said passageway to engage said arm to lock the same in said passageway, and resilient means extending in said passageway and adapted to be engaged by said'arm and forced out of the passageway thereby when the said arm is inserted from the top of the lock casing, and engaging the lend of the arm and obstructing said passageway and preventing the insertionof said arm when an attempt is made to insert said arm from the reverse direction with respect to said lock casing.

In a sliding shackle lock, the combination of a sliding shackle with a lock casing having a passageway through it to slidably receive an arm of said shackle and suitable mechanism having means adapted to extend into said passageway to engage said arm to lock the same in said passageway, and a leaf spring secured in said casing and having a free portion extending inwardly and downwardly into said passageway and adapted to yield under the influence of said arm and move out of said p-assageway as said arm is forced downwardly in Said passageway, but adapted to block with its free end any attempted insertion of the arm erroneously in the reverse direction.

4. In sliding shackle locks, a lock casing having the usual passageway for an arm of the sliding shackle, and a yielding element mounted in said casing and adapted to eX- tend into said passageway when the said arm is not inserted therein and having an abrupt edge presented toward the bottom of said casing and closely adjacent thereto to block the lower end of said passageway against the insertion of the said arm from the bottom of said casing.

In testimony whereof, I have signed my name to this specification at Lancaster, Pennsylvania, this 18th day of August, 1923.
